--------------------------------------------
Do I have to create another request to provide this potential patch?
> Mapreduce App master waits long to kill containers on lost nodes.

> Key: MAPREDUCE-6659
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-6659
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: mr-am
> Affects Versions: 2.6.0
> Reporter: Laxman
> Assignee: Jun Gong
>
> MR Application master waits for very long time to cleanup and relaunch the
> tasks on lost nodes. Wait time is actually 2.5 hours
> (ipc.client.connect.max.retries * ipc.client.connect.max.retries.on.timeouts
> * ipc.client.connect.timeout = 10 * 45 * 20 = 9000 seconds = 2.5 hours)
> Some similar issue related in RM-AM rpc protocol is fixed in YARN-3809.
> As fixed in YARN-3809, we may need to introduce new configurations to control
> this RPC retry behavior.
> Also, I feel this total retry time should honor and capped maximum to global
> task time out (mapreduce.task.timeout = 600000 default)
